html2docx

Common errors

• ModuleNotFoundError: No module named 'html2docx'

  cause The `html2docx` package is not installed in the current Python environment, or the environment where the script is being run is not the one where the package was installed.
  fix Run `pip install html2docx` in your terminal or ensure your virtual environment is activated.

• AttributeError: 'NoneType' object has no attribute 'find_all'

  cause This typically occurs when the HTML input provided to `parse_html_section` is empty, malformed, or could not be successfully parsed by `BeautifulSoup`, leading to an attempt to call methods on a `None` object.
  fix Ensure the `html_content` string is not empty and contains valid, well-formed HTML. Print `html_content` before parsing to debug its contents.

• ValueError: Invalid image path or data URL

  cause An `<img>` tag in the HTML specifies a source (`src`) that is either not a valid URL (absolute or local file path), an improperly formatted data URL, or the image file cannot be accessed/downloaded.
  fix Verify all image `src` attributes. For local files, ensure paths are correct relative to the script or absolute. For remote URLs, check network connectivity and URL validity. Ensure data URLs are base64 encoded correctly.

• The output DOCX document contains unstyled text or misses formatting (not an error, but a common issue)

  cause The source HTML relies heavily on CSS for styling that `html2docx` does not support or cannot translate directly into `python-docx` styles due to limitations of the DOCX format.
  fix Simplify HTML and CSS to use basic semantic tags (e.g., `<strong>`, `<em>`, `<h1>`-`<h6>`, `<ul>`, `<ol>`) and minimal inline styles that map well to Word document capabilities (e.g., `text-align`). Avoid complex CSS properties like `float`, `position`, or `display: flex`.

Warnings

• gotcha html2docx primarily translates HTML *structure and semantics* (e.g., `<h1>`, `<p>`, `<ul>`, `<strong>`) rather than exact *visual layout* dictated by complex CSS. Advanced CSS properties (e.g., `float`, `position`, `flexbox`) are often ignored or translated imperfectly due to DOCX format limitations.
  Fix: Simplify HTML and CSS to use basic semantic tags and inline styles that map well to Word document capabilities. Avoid relying on complex CSS for layout; use simpler constructs like `text-align` or basic list/paragraph styles.
• gotcha Relative image paths in the HTML may not resolve correctly when converting, especially if the DOCX is generated in a different context than the HTML was intended to be viewed. The library needs direct access to image files.
  Fix: Always use absolute URLs for remote images or ensure local image paths are absolute or correctly resolvable from the script's execution directory. Verify the image files exist and are accessible.
• gotcha The library expects well-formed and valid HTML. Malformed tags, unclosed elements, or overly complex/non-standard HTML structures can lead to unexpected output, missing content, or errors during parsing.
  Fix: Pre-process HTML with an HTML linter or a library like `BeautifulSoup` itself to clean up and ensure it's well-formed before passing it to `html2docx`. Avoid non-standard or deprecated HTML tags.

• Html2Docx

  from html2docx import Html2Docx

Quickstart

This quickstart demonstrates how to convert a string of HTML content into a .docx file using `html2docx`. It initializes `Html2Docx`, parses the HTML, and saves the resulting `python-docx` Document object to a temporary file, suitable for viewing or further processing.

import os
import tempfile
from html2docx import Html2Docx

# Example HTML content with basic structure and an external image
html_content = """
<h1>Hello World!</h1>
<p>This is a paragraph with some <strong>bold</strong> and <em>italic</em> text.</p>
<ul>
    <li>List Item 1</li>
    <li>List Item 2</li>
</ul>
<p style="text-align: center;">A centered paragraph.</p>

"""

# Initialize the parser
new_parser = Html2Docx()

# Parse the HTML and get a python-docx Document object
docx = new_parser.parse_html_section(html_content)

# Save the document to a temporary file
with tempfile.NamedTemporaryFile(suffix=".docx", delete=False) as temp_file:
    docx.save(temp_file.name)
    print(f"Generated DOCX saved to: {temp_file.name}")

# To view the file, uncomment the following line (might not work on all OSs)
# os.startfile(temp_file.name) # On Windows
# import subprocess; subprocess.call(['open', temp_file.name]) # On macOS

# In a real application, you might want to clean up the temp file after use
# os.remove(temp_file.name)
